Circulating fluidized bed is of low-temperature combustion,
therefore, nitrogen oxides emissions of such boiler is much lower
than that of coal-powder boiler, and such boiler could directly
desulfurized during combustion process. Circulating fluidized bed
boiler with high desulfurization rate is economical.Circulating fluidized bed boiler could adopt various coal types and
has high combustion efficiency, which is especially suitable for
low quality, low calorific value coal.

Structure Features

HD boilers are efficient, energy saving and environmental friendly,
which can help power plants actualize low pollutant emission based
on their advanced technology and reliable running.

High efficiency: combustion efficiency 96~99%, carbon content in
ash only about 2%, efficiency of boiler reaches 85%.- Suitable for various kinds of coal.- Load can be adjusted in the range of 25%~110%, average 5% in one
minute.- Clean combustion and environment friendly.- Use lime stone mixed into the fuel for desulfuration, rate up to
84%.- NOx emission capacity can be controlled to 150ppm or less.- Ash with low carbon content can be used for cement or
construction materials.
